jit.change Only pass different frames The jit.change object calculates the number of cells in which the current matrix differs from the previously received matrix, and based on this difference either passes the matrix or not. In mode 0 (default), the matrix is passed if the difference is greater than the specified threshold, otherwise not. In mode 1, the matrix is passed if the difference is less than the specified threshold, otherwise not. This object is particularly useful for reducing the density of dataflow and for motion tracking applications.
